Engineer, scientist, and executive Livanos talks about his company's fifty years of support for space science, the status of the James Webb Space Telescope, and his passionate concern about climate change and Earth observation.

Bruce Betts and Mat Kaplan consider the space food stick along with the night sky, and serve up another space trivia contest.
